💖 mips_cm_probe(9) — Kernel API Manual 💖

okay bestie, so this is mips_cm_probe, and it lives in the Kernel API Manual. it's short. it's iconic. it's literally one function. let's go 🎀

✨ NAME ✨

mips_cm_probe — probe for a Coherence Manager

like, it goes looking for a Coherence Manager. that's the whole job. main character energy fr 👑

---

🌸 SYNOPSIS 🌸

int mips_cm_probe (void );

---

🦋 ARGUMENTS 🦋

• void — no arguments. none. zero. she takes nothing and she gives everything 💅

---

⭐ DESCRIPTION ⭐

so the vibe is: this function attempts to detect the presence of a Coherence Manager. like it's literally doing a vibe check on the hardware, asking "hello?? is a CM in there??" 🫶

returns 0 if a CM is successfully detected — slay, found her ✨

else it returns -errno — which is the dramatic way of saying "nope, no CM, here's the error code about it" 😭

ngl that's it. that's the whole function. short and iconic, no notes.
